ULECIFICATION forming part of Letters Patent No. 303,741, dated August 19, 1884.

Application filed February 23, 1884.

derson, in the county of Madison and State of have invented a new and useful of which the following is a specibeing had to the accompa- Indiana, Sash-Lock, fication, reference nying drawings.

My invention relates to sash-fasteners; and it has for its object to provide a device of this character which shall be simple in its construction and positive and certain in its operation.

A further object of the invention is to pro vide a window-sash with a fastener, whereby it may belocked at any pointupon thelength of the frame.

\Vith these ends in view the invention consists in the improved construction and arran gement of parts hereinafter fully described, and pointed out in the claim.

In-the drawings, Figure 1 is a fr ont elevation of a window frame and sash, showing my improved fasten-er applied. Fig. 2 is an ele vation showing the corrugated disk engaged with the sash-frame to hold the window in a raised position, and Fig. 3 is a perspectiveview of parts in detail.

In the accompanying drawings, in which like letters refer to corresponding parts in the several figures, A represents awindowframe, and B the window sash sliding therein, both of which are constructed in the ordinary manner, except that the window-frame is provided on its inner side, near the outer edge thereof, with a notch or recess, a.

- 0 represents a disk or button, which is secured to one of the sides of the sash by means of a screw or rivet, upon which it is adapted to turn. This disk or button 0 is provided on its upper side or end with an outwardly-projecting lug, D, which is adapted to enter the notches or recesses formed on the inner side of the window frame or casing. This disk or button 0 is made slightly heavier at its upper portion than at its lower end, or it may be said to be pivoted, eccentrically, so that the greater portion of its weight comes above the point where it is pivoted. The lower side of the following manner:

(No model.)

this button or disk is provided with a notch, c, which engages with a pivoted detent, F, secured adjacent thereto.

My improvement is applied and operates in The button is secured upon the side of the window-sash adjacent to the side of the window-frame, and when the window-sash is lowered the lug upon the button enters the recess in the side of the frame, and the detent is forced into the notch of the button, thus locking the sash to the frame. \Vheudesired to raise and hold the window at any point upon the frame, the disk or button O is-dropped, as shown in Fig. 2, so that its corrugated edge engages or bears against the frame,and in this manner securely holds the window-sash at any desired adjustment. To lower the window from the raised position shown in Fig. 2, it is only necessary to push the button or disk upwardly, when it will, by the weight of its end, (the button being overbalanced or eccentrically pivoted,) remain in a raised or upright position.

It will be seen from the above description that my improved sash-fastening is simple in its construction, and that its operation is positive and effective.

Having fully described my invention, what I claim as new, and desireto secure by Letters Patent, isi In a saslrlock, the window-frame provided with a notch or recess, a, in combination with the window-sash, a disk or button, mental in form and eccentrically pivoted to the sash, an outwardlyprojecting lug on the upper end of the disk or button, and adapted to enter the notch or recess a, said disk or button having a corrugated back and being heavier above its pivot-point, a notch, c, in the lower side of the disk or button, and a detent, F, pivoted to the sash and provided with a lip to engage the notch c, as set forth.

In testimony that I claim the foregoing as my own I have hereto, affixed my signature in presence of two witnesses.
